Assertion : Compressibility factor for non-ideal gases can be greater than 1 .
Reason: Non-ideal gases always exert higher pressure than expected.
Reason: Non-ideal gases always exert higher pressure than expected.
View answer and explanation
Correct option: C
If Assertion is correct but Reason is incorrect.
The correct answer is C because the compressibility factor (Z) can be greater than 1 for non-ideal gases, but non-ideal gases do not always exert higher pressure than expected.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
Consider the following statements for kinetic molecular theory of gases

b. At any particular time, different particles in the gas have different kinetic energies.
c. Collisions of gas molecules are perfectly inelastic in nature.
The correct statement(s) is/are The compressibility factor of an ideal gas is The relative strength of interionic/intermolecular forces in decreasing order is Compressibility factor of an ideal gas is
